    • 8196. Jones, B. June 2. Burglar and like alarms.-A fire-alarm, operated by the fall of a weight released by the fusion of wax on the outbreak of a fire, stated also to be applicable as a burglar alarm, comprises an alarm bell a, Figs. 1 and 3, the hammer of which is operated by means of a pin h mounted on a disk driven by the drum c, around which is wound a chain d carrying the weight. The drum is held stationary by means of the lever m bearing against the stop k. Through the arm l of the lever m pass a number of wires o held taut by springs p. Each wire is connected at its other end to a fusible release device. As shown in Fig. 4, the wire o is wound around a wheel 1 held in position by an easily removable stick of wax v the removal of which causes the release of the wire o, the movement of which causes one of the blocks r, Fig. 1 , to pull over the lever m, so releasing the drum and thus allowing the weight to actuate the bell.

    • A real-time pulse parameter estimator is disclosed herein. In one embodiment, an apparatus has pulse detection logic, an abnormal pulse filter, and a pulse parameter estimator. The pulse detection logic is operable to detect pulses and to record an arrival time of each detected pulse. The abnormal pulse filter is operable to analyze the arrival time of the detected pulses and to determine whether there are any abnormal pulses based on the analysis. In one embodiment, the abnormal pulse filter generates an adjusted time difference of arrival (TDOA) signal for a pulse, based on a determination that the pulse is abnormal. The pulse parameter estimator is operable to estimate a pulse parameter for the signal based on an analysis of the arrival times of the detected pulses and information pertaining to there being any abnormal pulses in the signal.

    • A wireless communications apparatus that it is useable as a spectrum analyzer and as a wireless receiver. The wireless communications apparatus has a radio circuit that is configured to receive EM radiation. Signal processing logic receives signals from the radio circuit based on the EM radiation. The signal processing logic has a receiver operational mode that processes the signals in accordance with a communication protocol and outputs data encoded in the signals to a host processor. The signal processing logic has a spectrum analyzer operational mode that generates frequency domain data and passes the frequency domain data to the host processor. The frequency domain data describe strength versus frequency of the EM radiation. The host processes the data in accordance with the configuration currently in use. Therefore, the wireless communications apparatus operates as a receiver in one operational mode and as a real-time spectrum analyzer in another operational mode.
